When it's time to escape domestic responsibilities, head for the trails wearing the men's Patagonia Short-Sleeved Fore Runner ?-Zip . Lightweight, with a deep-venting front zip that lets you quickly blow off heat while running, the Fore Runner wicks moisture, breathes and provides 30-UPF sun protection. The supersoft 100% polyester double-knit has updated styling and fit, with flat-lock seams (offset at the shoulder) for next-to-skin comfort. Other details: Gladiodor odor control for the garment, built-in reflectivity along the zipper and on the logos (front and back). Now with a locker loop at the inner back neck for convenient dry time.
